Physics Instruments

Consists of the following item
a) Nodal Upright: Consists of a combination of Signal & double lens holders on a mount roating along the vertical axis. The combination lens holders are adjustable in hight, and the
single & twin lens holders can either be moved together by rack & pinion or relative to each other by sliding. these motions can be read by individual pointers on a mm scale .
b) Mirror : Plain, inclinable with 3” steel C.P Stand
c) Optical slit : With fine machined cross slit, one surface white & the other optical black, with 3” steel C.P stem
d) Lamp House : an electric bulb is encased in a metal case with cord & pin It works o220VAC.

This newly designed Optical Bench, comes complete with the standard Light Source and Optical set. The light box itself is the light source and the lens and slabs in the optical set are used on the prism table. The study of colours and shadows id performed from hinged mirror end of the light box and the study of light rays is performed from the ray end of the light box with the various slits and filter fitted. The optical Bench and kit come complete with all accessories.

The Optical Bench comes complete with the following,
One 120mm long straight anodized aluminium bench with scale, Special mounting platform to support light box, Set of 8 glass convex lenses 50mm dia, Set of 4 glass concave lenses 50mm dia, Projection screen, 3 x Plastic lens holder, 1 x rotary prism table.
